As set forth in the beginning, the truck comprisesside frames 1supporting a bolster 2 and journal boxes 3. In one set of journal boxesis'a short axle 4 having a double flanged wheel "5. The other set ofjournal boxes support a long axle 6 having a double flanged Wheel 7 inthe same vertical longitudinal plane as the wheel 5 so that the truckmay travel upon a single rail 8. The

ends of theframes 1 are inset at the axle 6 with the ends of the axle prruding from v M I v I hate-ether, with ene eifddrake-freak?narreaeerthanit ap that meters m-ay the afxle.

Both casings will have detachable covers'so thateasy access may be had thereto for lubricating and inspection purposes,and the train of gears constitutes a speed reduction mechanism be tweenthe axle and the electric motor.

With the electric motor set to one sideyof the axle 6, and looselyheldjthereby so that" the axle may rotate in the journalbox of the motorcasing, it is obvious that the spring supported side of a motor may havevertical I movement and such movement will not interthe sides of saidtruck frame, an end framefere with the driving relation between themotor and the axle.

Now, with a motor at each end of the axle, it is obvious that power canbe easily transmitted thereto to drive'the wheel 7, and by insetting theends of the frames lit ispossible to place the motors very close to thesides of the truck and thus materially reduce the over all width of thetruck. This permits of the electric motors remaining under a car bodymounted on the truck with the motors in such positions that easy accessmay be had thereto. This is in contradistinction to motors arranged inthe trucks or between the trucks of a car body, and in myarrangement itis possible to arrange trucks very close together beneath a car body andat the same time use any desired brake rigging within the trucks. Thereare other advantages gained by my constructive arrangement of partswhich will be apparent to those skilled in car construction, and Whilein the drawing there is illustrated a preferred embodiment of myinvention, it is to be understood that the structural elements aresusceptible to such variations and modifications as fall within thescope of the appended claims. What I claim is 1. The combination of amonorail truck having wheels, a wheel axle extending from I on saidtruck frame, and operating means supported by said end frame and wheelaxle and adapted to drive said axle.

2. The combination set forth in claim 1,

wherein said operating means includes an electric motor at each side ofsaid truck frame.

3. The combination set forth in claim 1,

wherein said operating means is yieldably supported by said endframe andtransmits power to saidwheel axle at a reduced speed.

4. The combination of a truck having wheels one in advance of the otherand one end of said truck narrower than the other end, anend frame atthe narrow end of 1 ,said truck, and power means at each side of saidtruck yieldably supported by said end frame and adapted to drive one ofsaid wheels.

5. The combination set forth in claim 4,

wherein-the wheel at the narrow end of the truck has a long axle, andsaid power means is in the form of an electric motor on each end of saidlong wheel axle.

6. A monorail truck comprising frames, a wheel at each end'of said truckbetween said frames, a long axle for one of said wheels, electric motorsfor driving said long wheel axle, and means supported from each frameparallel to the ends of said wheel axle adapted to cooperate therewithin supporting said electric motors. i a

7. A monorail truck as in claim 6, characterized by brackets on saidmotors, and

power I'GflHClllOIlHlQChitIllSIll supported by 9. A motor suspension asin claim8, chap acterized by there being a motor at each end of saidaxle.

10. A motor suspension as in claim 8, characterized by said motorsupporting means for transmitting power from said'motor to said axle atareduced speed.

11. A motor driven truck comprising transversely alini-ng motors, framesbetween said motors, a wheel between said frames having. an axleextending through said frames with the axle ends parallel to saidmotors, andmeans supported from said frames to cooperate with the axleends of said. wheel in supporting said motors.

12. The combination of a truck having a single driven wheel, motorsoutside of said truck for driving said wheel, said motors havingarmature shafts in a common axis transversely of said trnclrfland meansat two sides of each motor-parallel to the armature shaft thereofforsupporting said motors in an operative position.

In testimony whereof I affix my signature in presence of two witnesses.
